I've had to deal with State Farm and similar companies. Best tactic to use is simply demand they replace your truck exactly - same year, model, color, drivetrain, mileage, everything. It's your legal right. Hold firm to this demand, and be very picky...don't let them slide by with something worse than what you had. Chances are they won't be able to find an exact replacement that isn't halfway across the country, and will be far more willing to compensate you fairly if they know the exact replacement for your truck might end up costing them extra money.
Too many people don't realize this, and they just let the insurance companies dictate what they're entitled to and then of course they get shafted and are stuck with not enough money to replace their vehicle.
